Latest Optical vortex Stories
New fiber optic technology that transmits data along light beams that twist like a corkscrew rather than along straight lines could lead to increases in Internet bandwidth capacity.
Harvard School of Engineering and Applied Sciences At a time when communication networks are scrambling for ways to transmit more data over limited bandwidth, a type of twisted light wave is gaining new attention. Called an optical vortex or vortex beam, this complex beam resembles a corkscrew, with waves that rotate as they travel. Now, applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have created a new device that enables a conventional optical...
Scientists have demonstrated integrated arrays of emitters of "optical vortex beams" onto a silicon chip for the first time.
Researchers from the University of York are pioneering the development of electron microscopes which will allow scientists to examine a greater variety of materials in new revolutionary ways.
The fabric of space-time around spinning black holes should impart a â€œtwistâ€ in the property of light called orbital angular momentum.
The remarkable feat of tying light in knots has been achieved by a team of physicists working at the universities of Bristol, Glasgow and Southampton, UK, reports a paper in Nature Physics this week
Grover Swartzlander, an associate professor in The University of Arizona College of Optical Sciences, is developing devices that block out dazzling starlight, allowing astronomers to study planets in nearby solar systems.
